RADIATOR-VALVE-CONTROLLING DEVICE.

Specification of Iletters Patent.

Patented Oct. 17, 19 16.

Application filed February 27, 1915. Serial No. 11,087.

To all to ham it may concern Be it known that I, ALBERT P. BRooMELL, acitizen of the United States, and a resident of York, in the countyof'York and State of Pennsylvania, have invented a certain new and.useful Improvement in Hadiator-Valve-Controlling Devices, of Which thefollowing is a specification.

My invention relates to improvements in radiator valve controllingdevices, and it consists in the combinations, constructions, andarrangements herein described and claimed.

An object of my invention is to provide a device to be used inconnection with atmospheric vapor or vacuum heating systems where thereis no pressure in the return pipe, for automatically closing the inletvalve when the radiator is full of steam.

A further object of my invention is to provide a device of the typedescribed, which will prevent the waste of steam that is bound to occurwhen the steam passes out through the return pipe by controlling theamount of steam delivered to the radiator.

A further object of my invention is to' provide a device of the typedescribed in which such control is effected by a thermostatic memberhaving communication with the bottom of the radiator, and so arranged asto operate a valve disposed in the inlet pipe.

Other objects and advantages will appear in the following specificationand the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings forming part ofthis application, in which Figure 1 is a view of the radiator showing myinvention applied thereto, certain parts being shown in section; andFig. 2 is a section along the line 22 of Fig. 1.

As stated before, this device is intended for use in steam heatingsystems where there is no pressure in the return pipe, said return pipebeing open to the atmosphere or being connectedto a vacuum pump.

In carrying out my invention, I make use of a radiator such as thatshown at 1 in Fig. 1, of the usual type, an inlet pipe 2 connects withthe main supply pipe (not shown), and communicates at its top with avalve casing 3. This valve casing 3 communicates in turn with theradiator 1 by means of an intermediate pipe 4. Valve casing 3 isdesigned box 10 and is secured to a member 11 which is arranged totelescope with a portion of the stuffing box 10 and which houses aspring 12 that normally tends to keep the valve 8 open.

At the bottom of the radiator 1 and preferably at the inlet end of theradiator, is a pipe 13 which communicates with a housing 1 1 for athermostatic member 15 which is preferably of the bellows type and whichis designed to be filled with a volatile fluid that expands when steamenters the housing 14. The housing 14 is provided with a top 16 havingan opening 17 through which a pipe 18-extends, this pipe being securedto the telescopic member 11. The opening, 17

is large enough to permit the slow escape of air from the housing 14when the steam enters the housing, as will be explained later. 1

The'inlet pipe 2 communicates with the space below the partition 6 inthe extension 3* of the valve casing 3.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood.

Steam entering the pipe 2 passes below the partition 6, thence throughthe opening 7, andif' the valve in the casing 3 is open, past the valve,through the pipe 4, and into the radiator. As soon as the steam fillsthe radiator, further entrance of steam Will cause it to pass throughthe pipe 13 and into the housing 14:, where it will give up its heat tothe thermostatic member 15 causing the expansion of the latter. Thiswill move the pipe 18 upwardly, thereby causing the closing of the valve8 so as to shut off further entrance of steam.

As the steam begins to condense and the radiator grows colder, thethermostatic member 15 will contract and with the aid of the spring 12will cause the opening of the valve 8, thereby admitting steam. There isof course an alternate expansion and conaccomplished, as stated above,by means of the handle 5.

The device is simple in construction, and positive in operation, and canbe very readily applied to radiators of existing type or to systems ofthe kinds mentioned.

lVhile I have shown a pipe 18 as being the connection between thethermostatic member 15 and the telescopic member 11, it will beunderstood that I use a pipe simply because the latter is a convenientform of connection, being light in proportion to its strength, but itwill be understood that this pipe is not intended to establishcommunication between these members, but is simply a means ofcommunicatingthe movement of one member to the other, and may bereplaced by a solid rod or any other suitable form of connecting member.

1. The combination with a radiator having an inlet pipe and areturnpipe, of a' an auxiliary valve adapted to close said opening, asteam supply pipe communicating with said extension on the same side ofthe partition as the auxiliary valve, a housing, a pipe for establishingcommunication with the interior of said housing and housing forconnecting said thermostatic member with said auxiliary valve, and aspring disposed in close proximity to said auxiliary valve for normallykeeping the latter open. I

2. The combination with a radiator having an inlet and a return pipe, ofa valve casing communicating with said inlet pipe and being providedwith a valve adapted to be operated manually, said valve casing havingan extension, a partition within said extension provided with anopening, an auxiliary valve adapted to close said opening, a spring fornormally keeping said auxiliary valve in position to permit free passageof steam through the opening, a steam supply pipe communicating withsaid extension on the same side of the partition as does the valve, ahousing, means for establishing communication between the housing andthe interior of the radiator at the bottom thereof and at the endopposite the return pipe, a thermostatic bellows disposed within saidhousing, a rod arranged to project through one end of said housing forconnecting said thermostatic bellows with the auxiliary valve, saidthermostatic bellows being operated by the passage of steam from thebottom of the radiator into the housing, brought into position to shutoff the incomlng steam.
